PICKUP(8)                                               PICKUP(8)

       pickup - Postfix local mail pickup

       <b>pickup</b> [generic Postfix daemon options]

       The  <b>pickup</b>  daemon waits for hints that new mail has been
       dropped into the <b>maildrop</b> directory, and feeds it into the
       <a href="cleanup.8.html"><b>cleanup</b>(8)</a>  daemon.  Ill-formatted files are deleted with-
       out notifying the originator.  This program expects to  be
       run from the <a href="master.8.html"><b>master</b>(8)</a> process manager.

       None. The <b>pickup</b> daemon does not interact with the outside

       The <b>pickup</b> daemon is  moderately  security  sensitive.  It
       runs  with  fixed  low privilege and can run in a chrooted
       environment.  However, the program reads files from poten-
       tially  hostile  users.   The <b>pickup</b> daemon opens no files
       for writing, is careful about  what  files  it  opens  for
       reading, and does not actually touch any data that is sent
       to its public service endpoint.

       Problems and transactions are logged to <b>syslogd</b>(8).

       The <b>pickup</b> daemon copies mail from file to the  <a href="cleanup.8.html"><b>cleanup</b>(8)</a>
       daemon.   It could avoid message copying overhead by send-
       ing a file descriptor instead of file data, but  then  the
       already  complex <a href="cleanup.8.html"><b>cleanup</b>(8)</a> daemon would have to deal with
       unfiltered user data.

       The following <b>main.cf</b> parameters are  especially  relevant
       to  this  program. See the Postfix <b>main.cf</b> file for syntax
       details and for default values.  Use  the  <b>postfix</b>  <b>reload</b>
       command after a configuration change.

<b>Content</b> <b>inspection</b> <b>controls</b>
              The  name of a mail delivery transport that filters
              mail and that either bounces mail or re-injects the
              result  back into Postfix.  This parameter uses the
              same syntax as the right-hand  side  of  a  Postfix
              transport table.

              Address  to send a copy of each message that enters
              the system.

              Top-level directory of the Postfix queue.
